What mistake did Andy make ?

Answers

Answer 1

Answer:

The mistake that Andy made was on step 2 when he multiplied only the variables by 12.

Step-by-step explanation:

When you're solving an equation and are multiplying one side by a number, you need to multiply the other side by that number as well to keep the equation true. Since Andy multiplied only the variables and not the constants on each side of the equation, that means the equation would no longer be valid, and solving it would provide a wrong answer.

Answer:

person above me is right. that's is the answer.

Answer:

AB = 10 m

Step-by-step explanation:

Given that <ACB = <ECD, then triangles ABC and EDC are similar.

Let the height of the solar panel (AB) be represented by x. Thus by comparing the triangles, we have;

[tex]\frac{x}{6}[/tex] = [tex]\frac{45}{75}[/tex]

45x = 6 x 75

45x = 450

x = [tex]\frac{450}{45}[/tex]

x = 10

The height of the solar panel is determined to be 10 m.

Angie and Kenny play online video games. Angie buys 2 software packages and 3 months of game play. Kenny buys 1 software package and 1 month of game play. Each software package costs $30. If their total cost is $170, what is the cost of one month of game play?

Answers

Answer:

$20

Step-by-step explanation:

Kenny's gameplay: 1 month

Angie's gameplay: 3 months

1+3= 4

Kenny bought 1 software pack

Angie bought 2 software packs

1+2= 3

Each software package= $30

So 30×3= 90

Total cost= $170

170-90= 80

80÷4= $20

1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%

2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different

3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

For problems 11 and 12, find the area of the figure. Round your answer to the nearest tenth, if necessary.

Answers

Answer:

Step-by-step explanation:

11)

A= (B x H)/2

A= (2.9x3.2)/2= 4.64cm²

12)

A= (B+b)H /2

A= (12+10)5.6 /2 = 61.6in

Answer:

I think that the answer might be 9.30 for the first one and the second one I think is 670.

Step-by-step explanation:

To find the area, you have to multiply the height and width for the two figures.

3.2 × 2.9 = 9.28

12 × 10 × 5.6 = 672

I think you round those to the nearest tenth. 9.28 would be 9.30 and 672 would be 670. I hope this answers your question.

He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States. The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict.Read the passage from the website: www.expandingcountries.edu/unitedstates/louisianapurchaseThe Louisiana Purchase doubled the size of the United States and vastly increased its resources and riches. The roles of the president and the Constitution were also defined, as it was determined that the president could purchase the land without consulting Congress. Despite the advantages of expanding westward, one prominent disadvantage was the growing tension between slave states and free states regarding whether new states would permit slavery. The opportunity to grow a nation would endanger its very survival during the Civil War.Which of the following text based responses correctly answers the following question: How did the Louisiana purchase benefit the United States? Use both texts to find the best response. aPioneers began to farm the new land or use other natural resources. Some of these people used the Mississippi River and the Port of New Orleans to ship their products. This purchase clarified the Constitution, increased riches, and led to buying more land. bPresident Thomas Jefferson believed that for Americans to be virtuous and free, they needed to farm land.
